Neuronal Models of Cognitive Functions Associated with the Prefrontal Cortex

Abstract

Understanding the neural bases of cognition has become a scientifically tractable problem, and neurally plausible models are proposed to establish a causal link between biological structure and cognitive function. To this end, levels of organization have to be defined within the functional architecture of neuronal systems. Transitions from any one of these interacting levels to the next are viewed in an evolutionary perspective. They are assumed to involve: 1. the production of multiple transient variations and 2. the selection of some of them by higher levels via the interaction with the outside world.
